In the United States, Tax Season descends upon the country every April, requiring millions of Americans to spend hours deciphering cryptic documents and performing complex math just to figure out what they owe. Wouldn't it be grand if there was a way for a computer to take all the relevant documents and extract out exactly what the IRS is looking for? Lending Document AI from Google Cloud supports common document types used for Income Tax Filing, such as W-2s and 1099s. These advancements in machine learning technology now makes it possible to alleviate some anxiety leading up to April 15th.

Lending Document AI is a Document Understanding solution that allows for classification and parsing of documents commonly used in the mortgage lending industry. The data in these unstructured files is then converted into a structured format, which can be stored in a database or used for analysis and calculations. You can read more about the product in the announcement blog post. For this tax filing use case, we will focus on automatically classifying and parsing the 2020 editions of the following forms:

• 1099-DIV

• 1099-INT

• 1099-MISC

• 1099-NEC

This sample application creates an automated pipeline where the user can bulk upload a collection of PDFs, the Lending Document Splitter & Classifier will classify each document and send each PDF to the appropriate specialized parser to extract the data, which can then be used to calculate an individual tax return and fill out a 1040 Form.

Overview

Let's explore how this application works. You can check out the sample code in this GitHub Repository. 

Here is an outline of the architecture of this application. As you can see, it utilizes Cloud Run and Firestore in Native Mode for the web application in addition to Document AI.
